Specification of Letters Patent.

1 '0 all whom it may concern Be it known that I, HENRY W. MORGAN, ofRochester, in the county of Monroe and State of New York, have inventedcertain new and useful Improvements in Nalling- Machines; and I dohereby declare the following to be a full, clear, and exact descriptionof the same; reference being had to the accompanying drawings. forming apart of this specification. and to the reference-numerals markedthereon.

The present invention relates to nailing machines and it has for itsobject to provide improved mechanism of this nature more particularlyadapted for driving a plurality of nails simultaneously into the severalsides of an object, the machine of the present embodiment being designedparticularly for nailing in the heads of kegs.

The improvements are further directed toward simplicity and towardpromoting convenience and speed in operation.

To these and other ends the invention consists in certain improvementsand combinations of parts all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims at the endof the specification.

In the drawings: Figure 1 is a perspective view of a keg nailing machineconstructed in accordance with and illustrating one 9. hodiment of myinvention taken from a point to the right and in front of the machine;Fig. .2 is a pcrs ective view taken from the right in rear 0 themachine; Fig. 3 is a top plan view of the carrying frame for the nailingunits showing the driving mechanism, the same beingtaken in horizontalsection through'the supporting frame substantially on the line 3-3 ofFig. 1; Fig. 4 is a detail section taken substantially on the line 4-4of Fig. 3 to show more particularly the manner of operating the naildrivers; Fig. 5 is a side elevation of one of the nail chucks; Fig. disa top plan view thereof; Fig. 7 is a section taken substantially on theline 77 of Fig. 6, and Fig. 8

is an end elevation of one of the nail chucks. Similar referencenumerals throughout the several figures indicate the same parts.

To first give an idea of the general arrangements of the machine it maybe said that in the present embodiment the keg or work iece is designedto remain stationary beneat a vertical y sliding mechanism that l isbrought down upon it to position a plu rality of nailing unitscircularly about the same, while after the nailing operation themechanism is raised to release the work piece which is removed andreplaced by another.

Referring more particularly to the drawings, 1 indicates a substantiallyvertical main supporting frame at the base of which is arranged the worksupport 2. The'latter may be of any suitable nature, being in thepresent instance shown to comprise a truck traveling on tracks 3 andforming art of a conveyer by means of which the regs are delivered toand removed from the machine, but it will be later understood that asimple platform or, for that matter, the floor upon which the machinerests, might be utilized in this-capacity.

V Slidable vertically up and down'above the work support on guides l onthe frame 1 is a preferably annular carrying frame 5 upon the upper sideof which are mounted a plurality of nailing units embodying chucks 6that are arranged radially to drive the nails toward a common center.The chucks are each independently adjustable toward and from the centerof the annular carrying frame in guides 7 being secured in adjusts 8operating in slots 9 in the frame, the latter being indicated in dottedlines in Fig. 4. The inner ends of the chucks are each preferablyprovided with depending fingers 10 that, in the resent instance, projectdownwardly within the central opening of the annular frame 5 and haveinclined faces 11, the purpose of which is to center the keg or workpiece properly with respect to the chucks as the latter are lowered uponit, as will be understood from an inspection of Fig. 5.

Each chuck comprises a lower portion 6 and an upper portion 12, theadjacent faces of which are suitably recessed to conjointly form thenail channel 13 and the channel for the driver ll. The latter isprovided with a cross head 15 at its outer end that travels in a way 16in the lower member 6 and is held in place by a cover plate 17 at thetop, while at the inner endof the nail channel a sutiicient recess isprovided for the accommodation of the lower yielding chuck jaw 18 which.is pivoted at 19 to the member 6 and pressedupwardly by a spring 20arranged in a pocket 21 in the'iatter.

position in any suitable manner, as by bolts The 0 osing ieldin jaw-22is yoke-shaped so tha f the upiier rendovable block 12 of the chuck maybe accommodated between 1ts arms 23, which are pivoted at 24 to themember 6, while the said block is undercut at 25 to accommodate the endof the j aw beneath it, this portion of the block 12 be ng also providedwith a ocket 26 containing a spring 27 which ears against the stud aw22.

The upper block 12 is itselfheld 111 place for relative movement towardand from the lower portion of the chuck by pins 28 on the latter fittingrecesses therein and by a yokeshaped clip 29 that straddles the block 12and has the lower hooked ends 30 of its arms detachably engaging pins orprojections 31 on the portion 6. This clip holds the block yieldin ly'inplace by the en agement therewith o a spring 32 arranged in a pocket 33in the block so that the latter may accommo date itself readilv toirregularities in the passage of the nail through the nail channel, andit will also be seen that the block is removable by simply detaching theclip 29 so that access may be had to the nail channel when necessary.The feed channel 34 that delivers the nails to the nail channel 13 isformed in the upper block 12 of the chuck, the nails entering at-itsmouth 35 from the nail feed, as will be hereinafter described.

The drivers 14 of all the nailing units are simultaneously operated bya'rock shaft 36 that is journaled at 37 in a bridge piece 38 spanningthe annular carrying frame 5 in a manner to support the latter so thatthe frame is virtually hung upon this shaft. Se cured to the lower endof the shaft as it projects through the bearing 37 is a member 39 havingupper and lower laterally projecting flanges 40 and 41 that are spacedlongitudinally of the shaft and to these flanges alternately are pivotedat 42 the respective'ends of connecting rods 43, the opposlte ends ofwhich have hooked portions 44 that enter at the sides of the ways 16 ofthe chucks and cooperate with the cross heads 15 of the drivers,theouter ends of the latter being provided with pins 45 with which thehooked portions engage to withdraw the drivers, while a ball 46 ispreferably interposed between the hooked portion 44 of each rod and themain portion of the cross head that receives the driving pressure toreduce friction. It will thus be seen that as the shaft 36 is rocked theconnecting rods will travel in and out and operate the drivers, and thepurpose of pivoting these connecting rods alternately to the flanges 40and 41 is to allow them to clear each other and not interfere when anextreme stroke is made. It is notthought necessary to further describethe manner of driving the nail.

The upper portion of the shaft 36 is slidably journaled at 47 in aforwardly extend ing bracket 48 on the supporting frame 1 and acounter-weight 49 is connected by a chain 50 passing over pulleys 51 and52 to the end ofthe shaft so that the shaft and the frame 5, that itcarries, may be raised and lowered with little effort on the guides 4,and for the purpose of thus manipulating it a downwardly projecting rackbar 53 is provided on the bracket 48, with which meshes a pinion 54'on ashaft 55 journaled in the bridge piece 38 of the same and provided withawheel or handle 56 that the operator may manipulate from the front ofthe machine, as the work pieces are put in place on the work support 2.

The function of the projections 10 on theseveralchucks for centering thelatter over the keg or workpiece as the frame 5 is lowcred, has beenbefore described, but in order to first properly approximate theposition of the work piece on the support, adjustable stops or abutmentsare provided on the frame 1 having the present form of laterallyprojecting screw-bolts 57 that are held in adjusted position bylock-nuts 58. The kegs are thrust against these when inserted and inorder to halt the downward movement. of the frame 5 carrying the nailingunits so that the latter will deliver at the proper point, as at thechime A of the keg B having the head C, (Fig. 5) adjustable stops 59 arethreaded into brackets 60 on the bridge piece 38 of the frame thatengage the top or head of the work piece as the frame is lowered.

The shaft 36 is driven by a shaft 61 journaled in brackets 62 and (Benthe main frame, which shaft 61 is itself driven through gearing 64 and65 from a shaft 66 that is in turn driven by gearing 67 and 68 from themain driving shaft 69 having a belt pulley '70 thereon. A suitableclutch mechanism (not shown), controlled by a hand lever 71 accessibleat the front. of the machine, throws the gearing .6465 between the shaft66 and the shaft 61 in or out of operation at the will of the operatorby disconnecting the gear 67 from shaft 66 or the reverse, so that theshaft 61, and with it the nail driving mechanism is operatedintermittently, as desired, from the continuously turning main drivingshaft only when the driving units are in proper coiiperation with thework piece.

The connections between the shaft 61 and the rock shaft 36 for operatingthe latter, comprise a crank 72 on the upper end of the shaft 61 towhich is attached a connecting rod 73. The other end of this connectingrod is pivoted at 74 to a crank 75 on a sleeve 76 that surrounds theshaft 36 within the bearing 47 on the bracket 48 and turns freely in thebearing while being locked against rotation on the shaft 36 in anysuitable manner, as by the key 77 that per-' nuts the shaft 36 to slidelongitudinally within the sleeve and bearing. The crank 72 is shorterthan the crank 7 5 so that as the former revolves with the shaft 61 the,

latter only oscillates and rocks the shaft 36 to operate the connectingrods 43 and actuate the drivers 14, as before described.

When the chucks 6 of the nailing unit are adjusted inwardly or outwardlyon their guide 7 to accommodate the machine to kegs or work pieces ofdifferent sizes, the limit of the throw of the drivers 14; must, ofcourse, be correspondingly changed, and to effect this I provide theconnecting rod 73 between the shafts 61 and 36 with threaded portions 78by means of which it may be -le11gthened or shortened and the crank 75thus be made to move through an arc of greater or less degree upon therotation of the crank 72;

The nails are fed to the months 35 of the feed passages 34 in'the upperblocks 12 of the various nailing units, through lower feed tube sections79 carried with the frame 5 that telescope upon upper sections 80leading from the usual, or any preferred form, of nail hoppers 81 sothat the upward and downward movement of the frame 5 does not interferewith the nail feed.

As to the other necessary accessories of the nailing machine, these havebeen shown generally in the drawings, but it is not thought that theyrequire any detailed description as they form no part of the presentinventi n.
